Detect if app is running in Slide Over or Split View mode in iOS 9

Question

In iOS 9, is it possible to detect when an app is running in iOS 9\'s Slide Over or Split View mode?

I\'ve tried reading through Apple\'s documentation on iOS 9 mult

Answer 1

Just another way to repackage all of this

extension UIApplication {
    public var isSplitOrSlideOver: Bool {
        guard let w = self.delegate?.window, let window = w else { return false }
        return !window.frame.equalTo(window.screen.bounds)
    }
}

then you can just

• UIApplication.shared.isSplitOrSlideOver in Swift
• UIApplication.sharedApplication.isSplitOrSlideOver in Objective-C

Note that, in Swift, the window object is a double optional... WTF!

For iOS 13+ (note, I haven't tested the iOS 13 code myself yet)

extension UIApplication {

    public var isSplitOrSlideOver: Bool {
        guard let window = self.windows.filter({ $0.isKeyWindow }).first else { return false }
        return !(window.frame.width == window.screen.bounds.width)
    }
}
